NcStar AR-15 Quick Release Picatinny Rail 3/4" Riser

The NcStar AR-15 Quick Release Picatinny Rail 3/4" Riser is an essential accessory for AR-15 platform shooters who require elevated optic mounting solutions. This riser is particularly beneficial for law enforcement and military marksmen who need to achieve proper sight picture alignment and reduce parallax error. Its design accommodates mid-length and carbine-length upper receivers, making it versatile for various applications.

Engineered with a 3/4-inch vertical rise, the riser positions optics at an optimal height-over-bore geometry for both close-quarters engagement and extended-range accuracy. The Picatinny-compatible top surface accepts all standard rail-mounted systems, including red dots, magnified scopes, and hybrid sights. The quick-release mechanism allows for tool-free removal, facilitating easy transitions during drills or equipment swaps.

Operators benefit from the ability to co-witness backup iron sights while maintaining a higher cheek weld for improved shooting comfort. Constructed from durable machined aluminum, this riser is designed to withstand the recoil of intermediate and rifle cartridges, ensuring zero shift resistance and repeatable performance. Weighing only 0.32 lbs, it adds negligible mass to your upper receiver assembly, making it ideal for patrol carbines, competition builds, and home-defense platforms.
